This release focused on supporting video features and scripting features. It's been a lot of under-the-hood changes. While it's still nowhere near complete, some video sites - in particular Youtube - now show their videos. Of course, a lot of files still don't work.

The plugin has seen some important bugfixes. The properties dialog has also become a lot nicer and you can even watch large files downloading.

Swfdec still is development software, but has also followed a rigid no-crashes-allowed policy. I believe it's stable enough now to be installed as a default plugin for people that can live with occasional crashes of their browser. But don't blame me if it does crash.
